I ‘m happy and I just want to write

In the second semester of graduate school, only five lectures are scheduled in my timetable, so I have a lot of spare time to study/for studying English. I especially , I want to improve my spoken English and written English. Having been on Italki for some/a few months already, I really appreciate the friends here who ever (ever is so often misused! it should usually be used in a question) have helped me with my English and I’m glad to help you with your Chinese however I can.
My name is 朱晓慧, so you can call me 啊慧（ā huì）. In some regions of China, people usually call each other '阿×' 'a-x' to each other, ; for example, a guy called 张辉 would be called 阿辉，or a girl called 高志兰 may be called 阿兰。My friends usually call me 啊慧。I think it’s a little corny to name myself 阿慧，so I use the homonymic character 啊 instead of 阿. Thus the name looks like very funny and special. 啊 is a grammatical particle (an exclamation or ejaculation) like “oh” and “ah” to express emotion like surprise , admiration. Certainly, it has another function(s) and can be used in many situations. In my name, I think it serves as an exclamation. 啊~~慧！
